Title Exploring the role of CII in current Spinning Dust Models

Author European Space Agency
Description We propose HIFI observations of the CII fine structure line at 158 micron (1.9THz) in 22
pointings distributed across four Galactic anomalous emission regions (the Perseus cloud,
LDN 1780, LDN 675 and LDN 1111). The currently favoured explanation for the observed
anomalous microwave emission is that of electric dipole radiation from rapidly rotating
small dust grains (PAHs and/or VSGs), commonly referred to as spinning dust. Although
this hypothesis predicts that the source of the excess emission is due to dust, the small
dust grains are sensitive to the ionisation state of the gas, and hence the spinning dust
models have a dependancy on the abundance of the major gas ions. CII observations will
enable us to investigate this dependancy, and combining these observations with the
available mid- to far-IR observations will permit a complete analysis of the role of both
the dust and gas in regions of anomalous emission. We request a total of 14.9 hrs of HIFI
observing time.

Mission Description Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
